BMW E36 aFe Cold-Air Intake Kits

Founded in 1999, Advanced Flow Engineering (aFe) produces high flow, high performance replacement air filters and complete cold-air intake systems for BMWs. Each precision-engineered intake component and filter offers excellent design and construction, lifetime cleanable cotton filters that breathe easier than paper filters, powder-coated heat shields to block out hot engine air, and measurable performance gains resulting in increased horse power and torque. aFe's reputation is fast growing as a manufacturer and designer of quality and functional intake kits with excellent fit and finish and reasonable cost.

aFe enigneers their kits for each individual model application, even designing air filters from scratch to maximize the available surface area of the low pressure zone. They then offer their intake components in packages that fit your tastes and needs -Replacement Performance Filter. A direct performance replacement filter for your stock air box.Dynamic Air Scoops. Metal scoops or ducts that create a 'ram-air' effect to the intake.Super Stock System. A performance filter combined with Dynamic Air Scoops and Throttle Body Spacer for power gains while keeping the OEM appearance.Stage 1 Kit. A cone-filter kit with vehicle-specific heat shield and intake tubing to replace a stock airbox.Stage 2 Kit. All of the components in a Stage 1 Kit plus additional intake tubing or ducting after the air box or air mass meter.Sealed Intake. A Stage 1 or 2 Kit with an enclosed airbox and heat shield. The filter area is maximized inside a vehicle-specific airbox and then sealed with a cover for a OEM-type appearance.

This eco-friendly air filter cleaner is for the aFe Pro Dry S performance air filter. Simply spray on and wash off and your Pro Dry S air filter is good to go. Please follow the instrucctions with the kit and you will have a lifetime of horsepower.

This air intake system produces up to 15 horsepower, 20 lbs. x ft. torque and out-flows the factory intake by up to 80%. Included in this system is a "oil free" conical air filter that uses three layers of progressive weave synthetic media for maximum convenience. The filter is constructed with 100% polyurethane for long life. This intake system also features a rotomolded tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. This intake system incorporates a unique coupling that smoothens the air transition into the intake tract, and also allows this kit to fit on both US and EURO Mass Air Flow Sensors. A one-piece black powder-coated heat shield requires little to no assembly for a hassle free installation.

5 Tall Conical Pro Dry S Air Filter: This intake utilizes a huge, 5" tall conical Pro Dry S performance air filter for increased performance. This 3-layer progressive, synthetic material air filter requires no oils and cleans with water and a brush for maximum convenience.

One-piece precision cut heat shield: The air filter is housed in a one-piece, black powdercoated 1.6mm heat shield that keeps warm engine air out for maximum performance. This one-piece heat shield uses factory mounting locations and comes with all hardware for a hassle-free installation.

Compatible with most aftermarket HIDs: This system was designed to clear larger style HID headlight housings.

One kit to Fit Both US and Euro HFMs: aFe has re-engineered their systems so that the same kit is used for either the US or Euro HFM. The filter and tubing was optimized for use with the 3.5" HFM and a special adapter was engineered to work with the stock 3.0" HFM. This is a bonus for cars with the stock HFM as they get the larger filter and intake tract! Note: on cars with a 3.5" HFM an adapter is required to fit the HFM to the stock throttle body boot. Select this from the options below. If you are removing the factory ASC traction control we recommend getting the Samco Silicone Intake Boot. Select this from the options below.

Please note: If you are planning to use a 3.5" HFM on your 1995 M3, be SURE you are using the correct software and fuel injectors.

This version has an oil-free filter media for less maintenance. For the best flowing filter, with the best performance gain, we always recommend the standard aFe "Pro5R " filter (which has a blue pre-oiled filter media), but this oil-free filter flows only slightly less than the blue Pro5R style aFe filter, and requires no re-oiling after cleaning the filter.

Prevent water, mud and sand from congesting your air intake system with the aFe Pre-Filter. This aFe Pre-Filter slips right over your performance air filter, adding an extra layer of defense against moisture, grime and other roadway filth, extending the cleaning interval of your aFe filter. Water is repelled by the proprietary hydrophobic treatment to the Pre-Filters polyester fabric, and the pre-filters uniformly spaced micron holes prevent debris .005 or larger from passing through. Best of all, using the Pre-Filter does not significantly diminish your air filters performancethe smooth rush of oxygen keeps rolling right into your engine. Visually, the Pre-Filter blends in seamlessly with your aFe Cold Air Intake System and other components under your hood.

This air intake system produces up to 20 horsepower, 25 lbs. x ft. torque and out-flows the factory intake by up to 80%. Included in this system is a washable/reusable conical air filter that uses five layers of oiled cotton gauze filter for maximum performance. This intake system also features a rotomolded tube that replaces the stock intake tract and directs increased air flow with improved volumetric efficiency for maximum performance. This intake system incorporates a unique coupling that smoothens the air transition into the intake tract, and also allows this kit to fit on both US and EURO Mass Air Flow Sensors. A one-piece black powder-coated heat shield requires little to no assembly for a hassle free installation.

5 aFe conical filter: aFe has maximized the space available in the E36 engine compartment to fit the largest available cone filter. For maximum flow and the highest horsepower gain, the Pro 5R oiled cotton gauze filter is used. The Pro 5R is a 5-layer progressive layered, oiled cotton gauze material that allows maximum air flow while trapping dust and dirt. It's a re-useable filter that needs only a shake and rinse to be cleaned and occasional re-oiling. This kit is also available with a maintenance free paper filter.

One-piece precision cut heat shield: The air filter is housed in a one-piece, black powdercoated 1.6mm heat shield that keeps warm engine air out for maximum performance. This one-piece heat shield uses factory mounting locations and comes with all hardware for a hassle-free installation.

Bring your aFe filter back to life with a Restore kit from aFe. Included is filter cleaner & replacement oil. These air filter oils is designed to not harm MAF sensors, while allowing the filter to catch as much debris as possible.

Our new intake boot for E36 M3 with S52 engine and 3.5" Euro HFM retains the stock ASC option while providing a full diameter tube to connect the HFM to the throttle body. Often the 3.5" HFM is used with the a reducer to fit onto the stock intake boot. This upgraded intake boot does not use the reducer which results in greater air flow to the throttle body.

This upgrade kit retains the ASC throttle body when upgrading to a 3.5" EURO MAF sensor. This coupling upgrade was designed to work with aFes P/N: 51-12392 / 54-12392, but it can also be used with other competitors intakes. The coupling is constructed of polyurethane for strength and durability. This engineered coupling upgrade increases air flow and velocity by controlling the air intake dynamics. This is a very simple bolt-on product and requires no cutting or drilling.

The Silver Bullet throttle body spacer creates turbulence in the air flow just prior to entry into the engine increasing horsepower, torque and improving throttle response. In recent dyno testing by aFe, this throttle body spacer produced +4hp and +8lbs. x ft. torque (measured on E36 M3 with S52 engine) . The Silver Bullet throttle body spacers are constructed out of durable T-6061 billet aluminum and using a unique serrated/helix entry to create turbulence at the manifold while eliminating the annoying whistle found in other helix only throttle spacers. Great power per dollar performance.
